A new, organocatalytic approach to the hydrolytic deprotection of dithianes has been developed involving a low-toxicity imidazolium-ion-based catalyst in an aqueous medium. A complimentary solvent-free method without added water and involving a sacrificial aldehyde is also reported. The catalyst does not appear to operate by a specific-acid catalysis mechanism.
已经开发了一种新的有机催化方法来水解二噻烷的脱保护,该方法涉及在水性介质中使用低毒性咪唑鎓离子基催化剂。还报告了一种不加水且涉及牺牲醛的免费无溶剂方法。该催化剂似乎不是通过特定的酸催化机制起作用。
